MySQL Connector/NET integrates support for Entity Framework Core (EF Core). The requirements and configuration of EF Core depend on the version of Connector/NET installed and the features that you require. Use the table that follows to evaluate the minimum requirements.

Use the docker exec -it command to start a mysql client inside the Docker container you have started, like the following: docker exec -it mysql1 mysql -uroot -p When asked, enter the generated root password (see the last step in Starting a MySQL Server Instance above on how to find the password). Sep 23, 2020 Installing MySQL in docker container is an easy process which can be done by pulling a docker image, deploying the MySQL container and connecting to the MySQL Docker Container. Here at Bobcares, we have seen several such Docker related queries as part of our Docker Hosting Support for Docker users, web hosts, and online service providers. It detects the server sql version to see if it should add that command or not. So I really need to have the right client version on my php image/container. This is my Dockerfile. FROM library/php:7.4-fpm RUN apt-get update && apt-get install -y default-mysql-client. Php mysql docker. Sep 06, 2021 Python mysqlclient multi-stage docker build. I’m trying to create a small size python image with mysqlclient for a flask API, this is the dockerfile: FROM python:3.7-slim as builder WORKDIR /build RUN apt update && apt install -y build-essential default-libmysqlclient-dev git ARG MYSQLCLIENTVERSION=v2.0.3 RUN git clone -branch.

General Requirements for EF Core Support

  • Connector/NET 8.0

  • MySQL 5.7 or MySQL 8.0 server

  • Entity Framework Core packages:

    • MySql.EntityFrameworkCore 5.0.0+m8.0.2x and 3.1.10+m8.0.2x (Connector/NET 8.0.23 and higher on .NET)

    • MySql.Data.EntityFrameworkCore 8.0.2x (Connector/NET 8.0.22 and earlier)

  • An implementation of .NET Standard) or .NET Framework that is supported by Connector/NET (see Table 7.2, “Connector/NET Versions and Entity Framework Core Support”)

  • .NET .NET Core SDK

    • .NET 5.0 for all supported platforms: https://dotnet.microsoft.com/download/dotnet/5.0

    • .NET Core for Microsoft Windows: https://www.microsoft.com/net/core#windowscmd

    • .NET Core for Linux: https://www.microsoft.com/net/core#linuxredhat

    • .NET Core for macOS: https://www.microsoft.com/net/core#macos

    • Docker: https://www.microsoft.com/net/core#dockercmd

  • Optional: Microsoft Visual Studio 2015, 2017, 2019, or Code

    For EF Core 3.1, Visual Studio 2019 version 16.3 is the minimum.

Configuration with MySQL

Docker Build Mysqlclient

To use Entity Framework Core with a MySQL database, do the following:

  1. Install the NuGet package.

    When you install either the MySql.EntityFrameworkCore or MySql.Data.EntityFrameworkCore package, all of the related packages required to run your application are installed for you. For instructions on adding a NuGet package, see the relevant Microsoft documentation.

  2. In the class that derives from the DbContext class, override the OnConfiguring method to set the MySQL data provider with UseMySQL. The following example shows how to set the provider using a generic connection string in C#.

Limitations

The Connector/NET implementation of EF Core has the following limitations:
